Quantum irreversibility and noise in mesoscopic devices

Irreversibility in quantum processes in the Bunimovich stadium and rectangular billiard in the presence of noise is studied. For this purpose, a novel method based on Loschmidt echo and quantum trajectories, as defined in the de Broglie-Bohm formulation, is used. Our results indicate that the dynami...
